Abstract

FIELD: removal of solid remains from flowing medium. SUBSTANCE: the substance subject to treatment with consistency of flowing medium is continuously applied in form of thin layer to upper surface 4t of heat-exchange wall 40. This wall is heated up to temperature sufficient for rapid evaporation of water and/or other volatile components of substance, and dry solid remains are withdrawn as soon as they are formed on surface 41 by means of scraping of side surface. Wall 40 is heated by means of steam produced due to evaporation, the steam is compressed and brought in contact with lower surface 42 of wall 40 to be condensed on it. In this case, liquid condensate 104 is subsequently removed. The offered method is low cost due to the fact that energy liberated in condensation is used on the other side of heat-exchange wall for evaporation. Some other substance may be also dried, particular, slurry of pig farms. EFFECT: higher efficiency.

Claims (1)

Субстанцию, подлежащую обработке, имеющую консистенцию текучей среды, непрерывно наносят в виде тонкого слоя на верхнюю поверхность теплообменной стенки, эту стенку нагревают до температуры, которая достаточна для того, чтобы заставить быстро испаряться воду и/или другие летучие компоненты, содержащиеся в субстанции, и сухие твердые остатки удаляются по мере их образования на упомянутой поверхности посредством скобления боковой поверхности; стенку нагревают посредством пара, который получают в результате испарения, упомянутый пар механически сжимается и затем приводится в соприкосновение с нижней поверхностью стенки с тем, чтобы конденсироваться на ней, при этом жидкий конденсат впоследствии удаляется. Этот способ извлечения является особенно дешевым вследствие того, что энергия, выделяемая при конденсации, используется на другой стороне теплообменной стенки для испарения. Могут быть высушены и другие субстанции, в частности шлам свиноферм.The substance to be processed, having the consistency of a fluid, is continuously applied as a thin layer on the upper surface of the heat exchange wall, this wall is heated to a temperature sufficient to cause water and / or other volatile components contained in the substance to quickly evaporate, and dry solid residues are removed as they form on said surface by scraping the side surface; the wall is heated by steam, which is obtained by evaporation, said steam is mechanically compressed and then brought into contact with the lower surface of the wall in order to condense on it, while the liquid condensate is subsequently removed. This extraction method is especially cheap due to the fact that the energy released by condensation is used on the other side of the heat exchange wall for evaporation. Other substances, in particular pig farm sludge, can also be dried.
